PRODUCT DESCRIPTION：YONAI Produce Competitive Black Silicon Carbide
Silicon Carbide is produced by melting silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open “Acheson” furnace. The result of this high temperature process is the crystalline formation of Silicon Carbide grains, of both Green and Black coloring. The color difference is due to the purity of the silicon carbide. Green SiC is of higher purity.
YONAI offers both Macro and Micro grit sizing. Our Silicon Carbide is offered in standard sizes, custom particle sizes, custom densities, and custom chemistries.
